Baby poorly after 8 week jabs?

My little boy had his 8 week vaccinations on Wednesday and he hasn't been right since. He's EBF and never normally has bad wind but since Thursday he's suffered from it terrible, kicking his legs up to his chest followed by bouts of uncontrollable screaming. He's also bringing his milk up more than he did before. Plenty of heavy wet nappies and no temp but he's so unsettled, awful seeing him so uncomfortable. Tried gripe water, gently cycling his legs etc. I guess I just want to know if anyone's baby reacted similarly and how long it lasted?
